How it works

  1. 1

    Drop in your track

    MP3, WAV, FLAC or M4A. The file never leaves your computer — nothing is uploaded.

  2. 2

    Pick a look

    Choose from 80+ reactive templates, set colours, cover art, text and effects. You see the result live.

  3. 3

    Export the video

    MP4 up to 4K, rendered faster than real time — for YouTube, Shorts, TikTok, Reels or Instagram.

What you get

  • Synthwave Horizon

    A GPU scene where the mountains are your spectrum.

  • Retro palettes

    Pink-violet by default; change both accents to match your cover.

  • VHS and grain

    Add tape wobble and grain for the full retro feel.

  • Nostalgic mood

    Or start from the Nostalgic mood preset.

Questions

Is it really free?

Yes. Make and download as many videos as you like, up to 4K. A small PulSound mark appears for a few seconds at the start and end of the video.

Who owns the video?

You do. The video is made on your device from your music; use it anywhere, including monetized YouTube channels.

Do you upload my track?

No. Your audio, images and the finished video never leave your computer — everything is rendered in your browser. There is nothing to install either.

Which browser should I use?

A current Chrome, Edge or Safari on a computer gives the fastest export (usually faster than real time). Firefox and phones work too, at real-time speed.
